To all whom, it ntay concern:

Be it known that I, GEoRe KRON, engineer, a subject of the German Emperor, residing in Malmo, 'inthe Kingdom of'Sweden, (whose full post-oflice address is 65 S6dra- Forstadsgatan, M'almo, aforesaid) have invented certain new and useful Improvements in and Connected with-Apparatus for Bind-' ing in the Toes of Footwear; and I do hereby declaregthe followin to be a full, clear, and exact description the invention, such as will enable others skilled in the art to which -it appertains to make and use the same, refthrough the said'binding in cord erence being had to the accompanying drawings, and to letters and figures of reference. marked thereon, which form a part of this specification. This invention has for its object to provide 1 an apparatus for binding inthe toepart of} frame boots and shoes.

The apparatus comprising the invention consists, essentially, of a pair of nipper-jawsj mechanism for holding a binding-in cord with a' reiulatable frictional resistance, the 25' said cord eing stretched between the ends of the two nipper-jaws, so that the same is laid with sufliclent tension, first, against the point of the toe, and, later, on both sides ackward as the shoe is moved forwardbe tween. the nippers with the toe in front; pushers for driving nails or equivalent fasteners and the upper-leather into the lip of the welt or of t e innersole, and means for adjusting the nip-. per jawsrelatively to each other to adapt them for right and left and crooked lasts.

' The pegging and binding-in of the toe-piece.

tus with certain parts broken away. -is a plan view-andshow's. the device'in ong tion for the insertion-of a shoe tobe operated piece thus ta es place. simultaneously, and any subuent alteration of the form is avoided.

Fig. Syis a section on the line C D of Fig. 6 throu h the bolt-m and one of the halves of the pus rod. Fig. 9 shows a toe-piece bound in according to this invention and shown, respectively, in

- longitudinal and transverse section.

, The nipper-box 6 consists of .two plates rigidly combined with each other by means of screws or the likea lower one 1 and an upper one 2'. Both plates are provided 'wit an opening 3 at the one edge thereof where the shoe is introduced. Between these two plates the nipper-jawsf are inserted, being guided-in grooyes in the plates corresponding to the curved parts of the shanks of the jaws f. l

The jaws f are pivot'ally combined with each other by meansof the central pin 5. With the plates. 1 and 2 is rigidly combined the cap 6, forming steering and bearing surfaces for the bars h i, by means of which the jawsf are put in motion.

The nipping-j aws f re connected,by means of links g, with the two halves h 1', respectively, of the longitudinally -divided pushrod. These two halves of the push-rod are guided'in the ca 6 of the nipper-casing e and are drawn to st er at one end by means of a set-ring 7c an set-screw 1, a bolt m arranged in'two semicylindrical recesses of the half push-rods being simultaneously tightened up with them. I 1 The opening-and closing of the jaws f "of the nippers is efiected by the displacement of a lever n, which operates on the bolt m, and thus on the push-rod, by the intermediary of 0 and causes the axial adjustment of the said. o is'simply'a head on t e bolt m, pivoted to 1 the lever n, so thatwhen said lever is actuated'the head 0 and thebolt m willmove. The slotted and pin fulcrum arrangement '77/ isv seenat the upper end of the lever n. v v The binding-in cord b, Figs. 1, 2, 3, 6, and

to the vnipp'er-casing c or, as shown, to one ofthe jaws of the nippersby the outwardly-pointed hook w, which is pushed through he said cord, or'in any suitable manner and-also ressed, by "means of an eccentric-bolt 1), an stretching-piece g, against 'thenipper-box, so that when the last r is moved toward thenipper-box the binding-cord-must overcome; aifrictional resist- 7 is attache latented. Jan. 23, 1906.-

in position to re Fig. 7 shows the ush-rod. The piece ance, Iwhich "is adapted to be regulated binding-cord b and tightening up more or less the stretchingpiece, and is then laid witha suitable tension in the edge of the jaws of the ni-ppers, which edge is provided with a groove :0 Both ends of the cord may also be held, if desired, by friction. The nipper-box is stationary while the last 1 is pushed in between the jawsf.

The arrangement for fastening the cord 1) consists of the rail 9, movably secured to the under parts of the plate 1. The outer end 9 of said rail 9 is bent at an angle upward, and between this angular part and the plates 1 and 2 the cord b can be fastened. This fastening takes place when the rail q is moved to the left in the drawings. This movement is effected by turning the crank-arm 11. An eccentric or cam p," secured to the crankshaft 12, then engages in a corresponding opening in the rail g, thereby causing said movement. The crank-shaft 12 is journaled in the plates 1 and 2.

After the lasting of the toe-piece has been eflected by the pushin forward of the last 7" and a' simultaneous c osing of the nipper jaws, the binding-cord then inserting itself automatically in the grooved working edge of the nipper-jaws, the nails or clamps, Fig. 5, are driven through the cord b and the upper-leather into the insole by means of the lever device, Figs. 2, 3, 6, and 7, mounted on the cover of the nipper-box. This lever device consists of a lever s and two links t, by means of which the two slides or pushers it are pushed into an arcuate groove 1) of the two jaws of the nippersf. The pegs, nails, or clamps are laid in an extension 42 of this groove before the prolongation w of the pushers and then by pressing the lever 8 forward are driven in. The fulcrum of the lever s is at the juncture of the two links t at s rela tive to the links t t. The stationary fulcrum a of the lever s is at the upper end of said lever and is stationary relative to the nipperbox e. 'The nails (1 are driventhroughthe the folded-over edge of the upper layer a into the lip d of the inner sole. The center of the arcuate groove is so placed that the nails are always driven approximately perpendicularly to the working edge of the nipper-jaws into the welt. The tongue-shaped prolongation w of the slide a is made elastic in order that it may slip up the inclined plane on which the nail or peg lFISS in t)he groove 1) in the nipper-jawsf. (See It has been assumed in the foregoing that the form (shape) of the shoe to be pegged and bound is a straight (symmetrical) one, the gegs, nails,or clamps being driven in at equal lstances from-the center line of the last. In the case of lasts which are not straight, or

right or left hand lasts, the distance at which the pegs are driven in from the center line must, owever, differ, and it is therefore necnipper-box e toward the last '1",

nippers varying from. the centralposition,

such position then being fixed again by retightening the set-screw Z.- It is evident that by this arrangement the jaws of the m pers may be adjusted both for straight an also {for more or less crooked and right or left hand asts.
